    I would use the Digi XBee3™ Cellular LTE-M Development Kit to create a GPS tracker.  I have another board I would like to connect to a cellular network. The board allows me to get GPS data and store it on an sd card but I would like to take that data and upload to a cloud database where I can use something like google maps to see where the device is at anytime.  The idea for this is to ultimately create a device that can be used for automatic check-ins at checkpoints for a city wide scavenger hunt game.

    I would use the Digi XBee3 development board to integer it on a remote operate vehicle ROV. and use it for telemetry.  The main function of this underwater vehicle will be get investigation data. For example Mark in maps seabed with poseidonia or other kind of natural species that should be protected. Or areas with plastic waste that should be cleaned.

    I would use the Digi XBee3™ Cellular LTE-M Development Kit to build a pet tracking device. The unit would use gps to
    relay position data over cellular to help locate a lost pet as well as give an initial alert if the animal leaves it’s preset geo-fence boundary location.
